A nurse is caring for a client who has a new prescription for interferon beta-1a 11 mcg subcutaneous three times weekly. Available is interferon beta-1a injection 22 mcg/0.5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.25"]
To calculate the dosage of interferon beta-1a for the client, the nurse should use the following formula:
Dose (mL) = Desired dose (mcg) / Available dose (mcg/mL)
Plugging in the values from the prescription and the medication label, we get:
Dose (mL) = 11 mcg / 22 mcg/0.5 mL
Simplifying the fraction, we get:
Dose (mL) = 0.5 / 2
Dividing both sides by 2, we get:
Dose (mL) = 0.25
Therefore, the nurse should administer 0.25 mL of interferon beta-1a per dose.

Correct Answer is ["100"]
Explanation
To determine the number of doses in the vial, we can use the information provided on the label. The vial contains 10 mL of insulin glargine, and each mL has a concentration of 100 units.
Number of units in the vial = Concentration * Volume
Number of units in the vial = 100 units/mL * 10 mL
Number of units in the vial = 1000 units
Therefore, the vial contains 1000 units of insulin glargine. Since the client is to receive 10 units per dose, we can calculate the number of doses:
Number of doses = Total units in the vial / Units per dose
Number of doses = 1000 units / 10 units/dose
Number of doses = 100 doses
So, the vial contains 100 doses of insulin glargine.
